-# Contributing to GreptimeDB
+# Welcome!
 
-Much appreciate for your interest in contributing to GreptimeDB! This document list some guidelines for contributing to our code base.
+Thanks a lot for considering contributing to GreptimeDB. We believe people like you would make GreptimeDB a great product. We intend to build a community where individuals can have open talks, show respect for one another, and speak with true ❤️. Meanwhile, we are to keep transparency and make your effort count here.
 
-To learn about the design of GreptimeDB, please refer to the [design docs](https://github.com/GrepTimeTeam/docs).
+Read the guidelines, and they can help you get started. Communicate with respect to developers maintaining and developing the project. In return, they should reciprocate that respect by addressing your issue, reviewing changes, as well as helping finalize and merge your pull requests.
 
-## Pull Requests
+Follow our [README](https://github.com/GreptimeTeam/greptimedb#readme) to get the whole picture of the project. To learn about the design of GreptimeDB, please refer to the [design docs](https://github.com/GrepTimeTeam/docs).
+
+## Your First Contribution

+
+- Follow the [Code of Conduct](https://github.com/GreptimeTeam/greptimedb/blob/develop/CODE_OF_CONDUCT.md)
+- Small changes make huge differences. We will happily accept a PR making a single character change if it helps move forward. Don't wait to have everything working.
+- Check the closed issues before opening your issue.
+- Try to follow the existing style of the code.

-To compile GreptimeDB from source, you'll need the following:
-- Rust
-- Protobuf
+## What is GreptimeDB
 
-#### Rust
+GreptimeDB is an open-source time-series database with a special focus on
+scalability, analytical capabilities and efficiency. It's designed to work on
+infrastructure of the cloud era, and users benefit from its elasticity and commodity
+storage.
 
-The easiest way to install Rust is to use [`rustup`](https://rustup.rs/), which will check our `rust-toolchain` file and install correct Rust version for you.
+Our core developers have been building time-series data platform
+for years. Based on their best-practices, GreptimeDB is born to give you:
 
-#### Protobuf
+- A standalone binary that scales to highly-available distributed cluster, providing a transparent experience for cluster users
+- Optimized columnar layout for handling time-series data; compacted, compressed, stored on various storage backends
+- Flexible index options, tackling high cardinality issues down
+- Distributed, parallel query execution, leveraging elastic computing resource
+- Native SQL, and Python scripting for advanced analytical scenarios
+- Widely adopted database protocols and APIs
+- Extensible table engine architecture for extensive workloads
 
-`protoc` is required for compiling `.proto` files. `protobuf` is available from
-major package manager on macos and linux distributions. You can find an
-installation instructions [here](https://grpc.io/docs/protoc-installation/).
+## Quick Start
 
-### Build the Docker Image
+### Build
+
+#### Build from Source
+
+To compile GreptimeDB from source, you'll need:
+
+- C/C++ Toolchain: provides basic tools for compiling and linking. This is
+  available as `build-essential` on ubuntu and similar name on other platforms.
+- Rust: the easiest way to install Rust is to use
+  [`rustup`](https://rustup.rs/), which will check our `rust-toolchain` file and
+  install correct Rust version for you.
+- Protobuf: `protoc` is required for compiling `.proto` files. `protobuf` is
+  available from major package manager on macos and linux distributions. You can
+  find an installation instructions [here](https://grpc.io/docs/protoc-installation/).
+  **Note that `protoc` version needs to be >= 3.15** because we have used the `optional`
+  keyword. You can check it with `protoc --version`.
+
+#### Build with Docker
+
+A docker image with necessary dependencies is provided:
 
 ```
 docker build --network host -f docker/Dockerfile -t greptimedb .
 ```
 
-## Usage
+### Run
 
-### Start Datanode
+Start GreptimeDB from source code, in standalone mode:
 
 ```
-// Start datanode with default options.
-cargo run -- datanode start
-
-OR
-
-// Start datanode with `http-addr` option.
-cargo run -- datanode start --http-addr=0.0.0.0:9999
-
-OR
-
-// Start datanode with `log-dir` and `log-level` options.
-cargo run -- --log-dir=logs --log-level=debug datanode start
+cargo run -- standalone start
 ```
 
-Start datanode with config file:
+Or if you built from docker:
 
 ```
-cargo run -- --log-dir=logs --log-level=debug datanode start -c ./config/datanode.example.toml
+docker run -p 4002:4002 -v "$(pwd):/tmp/greptimedb" greptime/greptimedb standalone start
 ```
 
-Start datanode by runing docker container:
+For more startup options, greptimedb's **distributed mode** and information
+about Kubernetes deployment, check our [docs](https://docs.greptime.com/).
 
-```
-docker run -p 3000:3000 \

 You can call `register_aggregate_function` method in query engine to register your aggregate function. To do that, you have to new an instance of struct `AggregateFunctionMeta`. The struct has three fields, first is the name of your aggregate function's name. The function name is case-sensitive due to DataFusion's restriction. We strongly recommend using lowercase for your name. If you have to use uppercase name, wrap your aggregate function with quotation marks. For example, if you define an aggregate function named "my_aggr", you can use "`SELECT MY_AGGR(x)`"; if you define "my_AGGR", you have to use "`SELECT "my_AGGR"(x)`".
 
-The second field is arg_counts ,the count of the arguments. Like accumulator `percentile`, caculating the p_number of the column. We need to input the value of column and the value of p to cacalate, and so the count of the arguments is two.
+The second field is arg_counts ,the count of the arguments. Like accumulator `percentile`, calculating the p_number of the column. We need to input the value of column and the value of p to cacalate, and so the count of the arguments is two.
 
 The third field is a function about how to create your accumulator creator that you defined in step 1 above. Create creator, that's a bit intertwined, but it is how we make DataFusion use a newly created aggregate function each time it executes a SQL, preventing the stored input types from affecting each other. The key detail can be starting looking at our `DfContextProviderAdapter` struct's `get_aggregate_meta` method.
